A PARANOID schizophrenic has been detained indefinitely after being discovered in London with an arsenal of weapons intent on killing the Prime Minister.

(CORR)Irfaq Naz was arrested with a cache of weapons, including a Samurai sword, stun gun, machete and hammers, when police smashed their way into his car.

The Middlesbrough taxi driver was spotted driving the wrong way down Camden High Street at about 4am on July 17.

Teesside Crown Court heard how the officers immediately recognised the 34-year-old was unstable and detained him under the mental health act.

A search of his home resulted in the discovery of baseball bats and a list of names including David Cameron and the Mayor of Middlesbrough Ray Mallon.

Last month he admitted possessing a prohibited weapon, three counts of possessing an offensive weapon, seven counts of having a bladed article and dangerous driving.

Consultant psychiatrist Pratish Thakker (CORR) told the court that Naz suffered from paranoid delusions of a grandiose scale believing there was an impending world war and the Mayor of Middlesbrough wanted to kill him.

"He was prepared for some kind of worldwide calamity and this stems from his beliefs and delusions," he said.

"If he was to become unwell again the risk could be serious. I can clearly see a link between his offences and his illness."

Judge Simon Bourne-Arton QC, the Recorder of Middlesbrough, imposed a hospital order with a restriction order meaning Naz, of Finsbury Street, can only be released with the permission of the Home Secretary.

The court heard that Naz had previously spent a month at Roseberry Park Hospital, Middlesbrough, as a mental health patient.

Outlining the case, Nick Dry, prosecuting, said: “A search of his vehicle revealed other weapons.

In the driver’s door panel were three eight-inch kitchen knives.

“Between the driver’s seat and door was a samurai sword, its sheath found nearby in the passenger foot well.

“From the rear seat officers recovered a claw hammer, a lump hammer and an axe which were in a plastic bag that also contained masking tape.

“In the boot they found a machete and a stun gun, shaped as a knuckleduster.”

In mitigation Peter Wishlade said: “It is a tragedy, to put it bluntly, that this has happened to this family.

“Mr Naz, when he is taking his medication, is perfectly calm, rational, articulate and easy to talk to, but unfortunately when not, he is inclined to delusions and regrettably he has endeavoured to carry them out.”

The Judge also disqualified Naz from driving for three years and ordered the weapons be destroyed.
